OSPF

- [Voiceover] Open shortest path first…is the quintessential link state protocol.…While a working group was formed…by the IATF in 1988 to develop OSPF,…V2 most recent RFC2328…was released in 1998.…OSPF V3 was created in 2008…with RFC5340 to support IPv6.…OSPF floods update LSAs to all neighbors in the network.…Areas were introduced to contain…these floods within reasonable boundaries.…

Routers that live only in a single area…are known as internal routers.…Those that are members of multiple areas,…are known as area border routers.…If a router injects routes into OSPF…from any other source,…it is known as an…autonomous system boundary router.…Routes that were created inside a single area…that a router is a member of are intra-area routes.…Routes that were created in other areas…are known as inter-area routes.…Routes that are injected from outside OSPF…are known as external.…

The backbone are is identified as area 0,…or 0.0.0.0.…The backbone is expected to be the core…because it is responsible for collecting…and injecting routes into other areas.…

With some simple hardware and routing protocols, you can connect offices in almost any location. Wide area networks (WANs) allow data to be shared securely and quickly over long distances. In this course, networking expert Greg Sowell describes how to set up WANs, including networking your workstations with switchs and connecting them to the Internet via a routing device.

He discusses different WAN technologies and features such as speeds, spans, and price points—including inexpensive options such as VPN. He then covers switches (the devices that connect computers in your building) and routers (devices that control the transmission of network data). Along the way, Greg shows how to build private connections, implement free networking over the Internet, build switch networks, and overlay-routed networks. He'll also introduce different routing protocols, such as OPSF link-state routing and distance-vector routing with RIPv2, EIGRP, and BGP.
